what is the answer to a-5<1

Answer:

x=1      -3(1+4)=-15

Step-by-step explanation:

-3(x+4)=-15

---------------

-3         -3

x+4= 5

  -4=-4

x=1

That should be right

-3(x+4)=-15

mutiply the bracket by -3

(-3)(x)= -3x

(-3)(4)=-12

-3x-12= -15

move -12 to the other side

sign changes from -12 to +12

-3x-12+12= -15+12

-3x= -15+12

-3x= -3

divide both sides by -3

to get + x and by itself

-3x/-3= -3/-3

Answer:

x= 1

The shorter piece is 37 cm

The longer piece is 48 cm:

Step-by-step explanation:

Divide 85 cm by 2 = 42.5

Divide 11 cm by 2 = 5.5

Add them together = 48 cm

85 cm - 48 cm = 37 cm

Length of 1st piece = 37 cm

Length of 2nd piece = x + 11 = 37 + 11 = 48 cm

Now -

Length of smaller piece = 37 cm

Length of larger piece = 48 cm

We have a board which is 85cm in length and must be cut so that one piece is 11cm longer than the other piece.

We have to find the length of each piece, length of the smaller piece, length of the larger piece.

Now -

x + (x + n) + (x + 2n) = 100

3x + 3n = 99

x + n = 33

n = 33 - x

According to the question, we have -

Length of board = 85cm.

Assume that the length of first piece be x. Then -

x + ( x + 11 ) = 85

2x + 11 = 85

2x = 74

x = 37

Hence -

Length of 1st piece = 37 cm

Length of 2nd piece = x + 11 = 37 + 11 = 48 cm

Now -

Length of smaller piece = 37 cm

Length of larger piece = 48 cm

Answer:

Step-by-step explanation:

Linear equation which represents the hours Yuson has left after x days is:

30-2x

Yuson must complete 30 hours of community service.

She does 2 hours each day.

i.e. in x days, hours of service done= 2x

After x days hours of service left= 30-2x

Hence, linear equation which represents the hours Yuson has left after x days is:

30-2x

The linear equation representing the hours Yuson has left after x days is y = 30 - 2x, where y is the remaining hours and x is the number of days.

The linear equation that represents the hours Yuson has left after x days is y = 30 - 2x.

This is because Yuson must complete 30 hours of community service, and she does 2 hours each day. The equation y = 30 - 2x represents the remaining hours (y) after x days.

For example, if it's the first day (x = 1), Yuson would have 30 - 2(1) = 28 hours left. If it's the second day (x = 2), Yuson would have 30 - 2(2) = 26 hours left, and so on.

The graph represents a functional relationship. On a coordinate plane, a straight line with a negative slope begins at point (1, 3), crosses the x-axis at (4, 0), and exits the plane at (18, negative 14). Which value is an input of the function?

A functional relation definition is a binary relation R⊂A×B between sets A and B, such as (a,b)∈R and (a,c)∈R imply b=c.

By determining whether a relation is a function involves making sure that for every input there is only one output. In order for a relation that called function, each X value must have one Y value whereas X has to have one Y value. X is the independent variable or input value, whereas Y is the dependent variable or output value

According to the graph attached, the linear function domain is equal to the interval [1,∞). All real numbers according to the graph is greater than or equal to 1. Whereas the linear function range is equal to the interval (-∞,3]. All real numbers less than or equal to 3, the value of 4 is an input of the function

Answer:140.07

Step-by-step explanation:

Answer:

$149.80

Step-by-step explanation:

To find sales tax you need to multiply the original cost of the item by the sales tax (converted into a decimal). In this case the sales tax converted would be 0.07. Now multiply that decimal by the original cost:

140 x 0.07 = 9.80

9.80 is how much you would be paying in sales tax. Now take this amount and add it to the original amount to get the total cost.

140 + 9.80 = 149.80

Answer:

x = 8.2

Step-by-step explanation:

Given

6.7x = 5.2x + 12.3 ( subtract 5.2x from both sides )

1.5x = 12.3 ( divide both sides by 1.5 )

x = 8.2

Answer:

8.2

Step-by-step explanation:

you can solve it by changing it to standard form

Thus, 67×10^-1x =52×10^-1x +123×10^-1

group like terms.

67×10^-1x -52×10^-1x =123×10^-1

15×10^-1x =123×10^-1

divide through by 15 ×10^-1

X= 123×10^-1/15×10^-1

X=41/5

X=8.2

Step-by-step explanation:

x = angle 1

3x + 12 = angle 2

angle 1 + angle 2 = 180

4x + 12 = 180

4x = 168

x = 42 = angle 1

180 - 42 = 138 = angle 2

X= the smaller smaller angle

180° = X + 3X + 12

180° - 12° = 4X

168° = 4X

X = 168 ÷ 4

X = 42°

The bigger angle is 3X + 12

= 3 × 42 + 12

= 126 + 12 = 138°

Answer: THIRD OPTION.

Step-by-step explanation:

Since  [tex]g(x) = -2f(x)[/tex], then [tex]g(x)[/tex] is:

[tex]g(x)=-2( x + 4)\\\\g(x)=-2x-8[/tex]

In order to find which table represents [tex]g(x) = -2f(x)[/tex] when [tex]f(x) = x + 4[/tex], you can follow these steps:

1. Substitute [tex]x=1[/tex] into the function [tex]g(x)=-2x-8[/tex]:

 [tex]g(1)=-2(1)-8\\\\g(1)=-10[/tex]

2. Substitute [tex]x=2[/tex] into the function [tex]g(x)=-2x-8[/tex]:

 [tex]g(2)=-2(2)-8\\\\g(2)=-12[/tex]

3. Substitute [tex]x=3[/tex] into the function [tex]g(x)=-2x-8[/tex]:

 [tex]g(3)=-2(3)-8\\\\g(3)=-14[/tex]

Notice that those ouput values (for [tex]x=1,\ x=2[/tex] and [tex]x=3[/tex]) matches with the table provided in the third option. That table represents [tex]g(x) = -2f(x)[/tex] when [tex]f(x) = x + 4[/tex]:

Hope this helps!

Answer:

Step-by-step explanation:

Looking at the values for [tex]y[/tex], you can see that each value is twice the previous value, which means that the missing value will be twice the previous value, which was 40, so the answer is 80.

When x = 4, the missing value is y = 80. therefore, option 80 is correct.

The table represents an exponential function, which can be expressed in the form y = ab^x, where "a" is the initial value (when x = 0), and "b" is the common ratio or base.

From the table, when x = 0, y = 5. This gives us the value of "a," which is 5.

Now, we can use this information to find the missing value when x = 4.

y = ab^x

y = 5 * b^4

To find "b," we can use another data point from the table, for example, when x = 1, y = 10:

10 = 5 * b^1

Now, solve for "b":

10 = 5b

Divide both sides by 5:

b = 10 / 5

b = 2

Now that we know the value of "b" is 2, we can find the missing value when x = 4:

y = 5 * 2^4

y = 5 * 16

y = 80

The statement that proves that triangle XYZ is an isosceles triangle is XZ = XY =5

isosceles triangles are triangles that have two equal sides

The coordinates are given as:

X = (1, 3)

Y = (4, -1)

Z = (5, 6)

Calculate the distances between the points using:

[tex]d =\sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

So, we have:

[tex]XY =\sqrt{(1 -4)^2 + (3 --1)^2}[/tex]

[tex]XY =5[/tex]

[tex]XZ =\sqrt{(1- 5)^2 + (3 -6)^2}[/tex]

[tex]XZ =5[/tex]

From the above computation, we have:

[tex]XY = XZ =5[/tex]

Hence, the statement that proves that triangle XYZ is an isosceles triangle is XZ = XY =5

Answer:

Emily can deduct $1975 for medical expenses.

Step-by-step explanation:

Emily is itemizing deductions on her federal income tax return and had $5200. Her AGI was $43,000.

We have:

The AGI is =$43,000

Medical expenses amount = $5200

If medical expenses are deductible to the extent that they exceed 7.5% or 0.075  of a taxpayer’s AGI, means  = 43,000 * 0.075 = $3225

Now the deductible amount is  = $5200 - $3225 =  $ 1975

Hence,Emily can deduct $1975 for medical expenses.

Answer:

Emily can deduct the $1,975 in medical expenses from her adjusted gross income.

Step-by-step explanation:

Before an individual could deduct medical expenses as long as they exceeded 7.5% of their adjusted gross income (currently it's 10%).

If Emily's AGI = $43,000, then she will be able to deduct medical expenses that exceed $3,225 (= $43,000 x 7.5%).

Emily's medical expense deductions = $5,200 - $3,225 = $1,975.

If this situation happened this year, Emily would have only been able to deduct $900  [= $5,200 - ($43,000 x 10%)]

Let

y -----> charge to move  household goods across town.

x ----> number of hours

we know that

Acme Movers

y=40x+175 ------> equation A

Hank’s Movers

y=75x ------> equation B

Equate equation A and equation B

75x=40x+175

solve for x
